These methods are available in a schema definition block given to Versionomy::Schema#create.
Add a module to the schema. All values that use this schema will include this module. This provides a way to add schema-specific capabilities to version numbers.
# File lib/versionomy/schema/wrapper.rb, line 248 def add_module(mod_) @modules << mod_ end
Create a field alias.
# File lib/versionomy/schema/wrapper.rb, line 239 def alias_field(alias_name_, field_name_) @aliases[alias_name_.to_sym] = field_name_.to_sym end
Provide a default value for the given type. The type should be :integer, :string, or :symbol. You must provide a default value that will be used for all fields of this type, unless explicitly overridden by the field.
# File lib/versionomy/schema/wrapper.rb, line 295 def default_value_for_type(type_, value_) @defaults[type_][:value] = value_ end
Create the root field.
Recognized options include:
:type |
Type of field. This should be :integer, :string, or :symbol. Default is :integer. |
:default_value |
Default value for the field if no value is explicitly set. Default is 0 for an integer field, the empty string for a string field, or the first symbol added for a symbol field. |
You may provide an optional block. Within the block, you may call methods of Versionomy::Schema::FieldBuilder to customize this field.
Raises Versionomy::Errors::IllegalValueError if the given default value is not legal.
Raises Versionomy::Errors::RangeOverlapError if a root field has already been created.
# File lib/versionomy/schema/wrapper.rb, line 229 def field(name_, opts_={}, &block_) if @field raise Errors::RangeOverlapError, "Root field already defined" end @field = Schema::Field.new(name_, opts_.merge(:master_builder => self), &block_) end
Provide a default bump procedure for the given type. The type should be :integer, :string, or :symbol. You must provide a block that takes a field value and returns the "bumped" value. This procedure will be used for all fields of this type, unless explicitly overridden by the field.
# File lib/versionomy/schema/wrapper.rb, line 259 def to_bump_type(type_, &block_) @defaults[type_][:bump] = block_ end
Provide a default canonicalization procedure for the given type. The type should be :integer, :string, or :symbol. You must provide a block that takes a field value and returns the canonical value. This procedure will be used for all fields of this type, unless explicitly overridden by the field.
# File lib/versionomy/schema/wrapper.rb, line 284 def to_canonicalize_type(type_, &block_) @defaults[type_][:canonicalize] = block_ end
Provide a default compare procedure for the given type. The type should be :integer, :string, or :symbol. You must provide a block that takes two values and returns a standard comparison result-- that is, a negative integer if the first value is less, 0 if the values are equal, or a positive integer if the first value is greater. This procedure will be used for all fields of this type, unless explicitly overridden by the field.
# File lib/versionomy/schema/wrapper.rb, line 273 def to_compare_type(type_, &block_) @defaults[type_][:compare] = block_ end
